STRAP-LOOP FOR CARRIAGES.

SPECIFICATION forming part of Letters Patent No. 445,105, dated January 20, 1891.

Application filed July 11, 1890. Serial No, 358,393. (No model.)

To alt who/nit may concern:

3e it known that I, DANIEL D. WHI NEY,

of Cornwall, county of Orange, State of New i which the following description, in connection with the accompanying drawings, is a specii fication, like letters on the drawings representing like parts.

In pole-carriages as now made the whittletrees are fastened to a cross-bar on the pole by suitable pivotal connections, and said cross-bar is itself connected ateach end to a suitable part of the gearing by safety-straps.

As a means for attaching the safety-straps to the cross-bar, loops are provided, which are secured to the under side of the cross-bars at one side of the pivotal connections of the whiffletrees.

This invention has for its object to construct an attaching device for such safetystraps by which the line of pull shall be in a direct line or under the pivotal connections of the whiffletrees, and to carry out this invention I have formed said loops directly on the under plate of the pivotal connections of said whiflietrees. Such construction I have found to be very much cheaper and more durable than an y form known to me, and also may be much more readily attached.

My invention consists in details of construction to be hereinafter pointed out.

Figure 1 shows in rear side view a portion of a whiftletree and cross-bar and pivotalconnections thereof and a loop for the safetystrap; Fig. 2, a vertical section of the parts shown in Fig. 1, taken on the dotted line a; .1;

I Fig. 3, a plan view of the under plate, showing the loop formed on it.

The whiifletree a and cross-bar Z2 and piv- 4o otal connections thereof, are all of usual or suitable construction.

The pivotal connection, as herein represented, comprises con tactplates c 0', bolt 0 under plate 0", having a socket formed in it to receive a yIelding cushion c', a washer c,

and nut 0 To provide a loop for the safety'strap (l, by which the ends of the cross-bar b are fastened to the gearing, and to so locate said loop that the strap will pull in a direct line with the bolt 0 I have formed said loop on the under plate 0 as represented at cl. This loop (1 may be formed cheaply in this way, and the plate 0 integral with which it is formed, will have three screws or means for holding itin place on the under side of the cross-bar b.

I claim The cross-bar, whifiletree, and whifiletreeconnections, combined with the under plate 0", having a socket formed therein on its under side, a yielding cushion in said socket, a retaining-n ut, and aloop (7 integral with said under plate and extended from its upper part at right angles thereto, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

DANIEL D. WHITNEY.
